27 hour render for 1.5 hour timeline??

I have a V8 timeline with three nested files, totaling 1h29minutes. There is some Mercalli and Neat Video FX in the first third, applied in the nested file. The rest has zero FX in the nested files, and Neat Video applied on the Master file's timeline, with some CartoonR on the last 3 minutes.

Pretty simple, no?

so it's been rendering for 9 hours and sez it's 33% finished.

The PC is a CoreDuo 3.2GH, 3.25GB ram. Render From and Render To hard drives are two internal SATA 7200rpm drives. RAW footage is HDV, rendering to DVDA widescreen template set to Good, 7MM average bitrate, single pass. I tried Best single and double pass, but it hung up on the dual pass, and I stopped the single pass.

Is there a more efficient way to get from the m2t files to mpeg2? I don't mind rendering overnight, but this ties up the mochine for a whole day as well.

shouldn't tie up your machine at all. vegas will easily let other programs use CPU cycles if necessary. Plus you're multi-core. Assign Vegas to core 1 only & then any other program to core 0. I did that last night to watch a DVD on my machine (well, Vegas to core 2 & 3, media player classic to core 0 & 1.

Hardware wise you're all set to go. Often, an unintended resize or opacity setting other than 100% can create havoc for rendering times. Check these settings on your tracks, and don't forget to also check the video bus.

NeatVideo is extremely good because (as far as I can tell) it uses very careful motion tracking. That makes it extremely slow.... Very likely the bottleneck. Reducing its (temporal) "radius" setting will speed things up at cost of denoisingness. Tradeoff.

Quickest way to convert m2t to mpeg2? That's a separate topic. File rename. That can be sufficient for some applications. Otherwise to do it properly I tend to use Mpeg StreamClip (free utility).

Neat video is extremely slow. Also, some fX can take a huge amount of time. I did a comparison years ago which is probably obsolete with V8, but still indicative of the fact that some fX are S-L-O-W:

Finally, going from HDV do MPEG-2 for DVD is a time-consuming process, even with a fast computer.

Oh, while you want to reduce your render time, if you are going from HDV to MPEG-2 for DVD, you really should use "Best" for rendering. It really shouldn't be called Best, but instead should be called something like "use this when rendering to a different resolution." That's what it's for.
